But what is the point of static compilation if maintainers update dependencies? Either dependencies defined by author or maintainers. Dynamic libraries just help to automate roll out.

And users would find outdated versions (maybe unmaintained). Current system update dependencies automatically or allow collaboration on life support (patched application, dependencies, config). It would be good to have alternative like container or virtual machine with snapshot from the days long past. But it should be clear this is not safe.
